Mojave Audio MA-301 FET
Multi-Pattern Condenser Microphone
The MA-301 FET is a solid-state version of the MA-300 tube mic. It could also be considered to be the multipattern version of the MA-201 FET. In keeping with the rest of the Mojave family of large-diaphragm mics, it uses a K67-style capsule and transformer-coupled output circuit.
The capsule is a 32mm (O.D.) model, with 26mm diaphragms made of 3-micron Mylar. The same capsule can be found in the other large-diaphragm Mojave mics.
The 301 includes a capacitative pad (-15dB) and a high-pass filter (-6dB/octave @ 100Hz). These features are not found on the two Cardioid LDCs from Mojave (MA-200, MA-201 FET); they were introduced on the MA-300 in late 2010. The switches for these features are located on the rear side of the MA-301 FET body, below the headbasket.
The pad, filter, and pattern switches add a significant amount of circuitry to the microphone, as compared to the minimalist approach of the MA201 Fet. The 301 also has a DC converter, which raises the polarization voltage to 55-60 V, and makes it somewhat easier to produce a figure-8 polar pattern with the mic’s 3-wire capsule. (See the Neumann U87 profile for more discussion of the use of K67 vs K87 capsules types in figure-8 microphones.)
The mic’s output transformer is from Jensen; the same model transformer is used in several of the other large-diaphragm Mojave microphones.
A small toggle switch located on the front of the microphone body provides selection of Cardioid, Omnidirectional, or Figure-8 polar patterns.
The mic was introduced at Winter NAMM 2012 in Anaheim, CA, and began shipping in early 2012.
The Mojave Audio MA-301 FET is also known as: MA301.
The mic was released in 2012.
